Scale insects are the most common pests on flowers and fruit trees. They often gather on branches, leaves and fruits to feed on plant juices. In severe cases, they can cause branches to wither or the whole plant to die. In addition, the secretion of scale insects can also induce sooty blotch, which is extremely harmful. Common scale insects include scale insects, camphor tree scale insects, chaff scale insects, Korean scale insects, mulberry scale insects, criminal scale insects and hibiscus scale insects.

50% malathion 1500 times solution or 2.5% deltamethrin 3000 times solution can be used to spray pesticides. Spray every 7 days 1 time, and spray continuously for 2-3 times.

Note: These drugs are toxic, so use them with caution.
